Problem 5

[deanhystad]

What is the purpose of this line?

for value in z:

You don't ever use value for anything and I see no reason for doing this loop.

It also isn't a solution to the problem. You're supposed to insert the count in the string, not print the count. The result should be the original string with no duplicate characters in a row, and a count following each character. In their example the input is 'cooooooooooooooooolkangaroo' and the output 'c1o17l1k1a1n1g1a1r1o2'.

As for the awkward while loop, why not do this instead?

for i in range(len(z)-1):

I think this makes more sense though:

for i in range(1, len(z)):

Or even better

for c in z[1:]:
